ST. LOUIS -As a reminder, The Missouri Department of Transportation has scheduled a weekend closure of all lanes of westbound I-70.

Current plans call for crews to close all lanes of westbound I-70 downtown between the Poplar Street Bridge and Pine Street starting at 8 p.m. Saturday, February 8, weather permitting.

The department will also close a lane on eastbound I-70 at that time, with full closures of eastbound I-70 for up to 15 minutes.

Crews will be installing girders over the interstate for the new Walnut Street bridge.

All interstate lanes are projected to reopen by noon Sunday, February 9.

This work is part of preparations for the CityArchRiver Park Over the Highway project.

The detour for the westbound interstate will be to exit onto northbound Memorial Drive and continue on 3rd Street to the ramp to westbound I-70 at the Martin Luther King Bridge.

The Eads Bridge and the ramp from the Poplar Street Bridge to northbound Memorial will also be closed, starting at 6 p.m. Saturday February 8, to ensure that interstate traffic moves smoothly. They will reopen when the interstate opens at noon Sunday.

The work is part of the overall improvements to access between downtown and the interstate as part of the Park Over the Highway project. Crews will continue to work around Memorial Drive and the interstate ramps near Pine this winter and spring. It is a portion of CityArchRiver 2015, a transformational project that will enhance the Gateway Arch experience for all visitors. The project will create a seamless park experience from the city to the Mississippi River, providing visitors with a more vibrant and safer place to visit, enjoy, and return. This work will not significantly impact access to the Gateway Arch, which remains open during construction.

Information about additional closures or traffic changes will be released when available.
